Heliblob: your brain wiring worries me.
Humans constantly evaluate risk. Some of them choose to ignore the warnings and end up as dead as the superbike rider I saw in bits down a motorway recently, having lost a battle with a truck.
But most of the ones who step into a helicopter for one-on-one instruction are constantly evaluated as a risk by their instructor. That instructor, normally, would like to continue life unimpeded by sticks, wheelchairs or coffins.
I used to be a racing instructor. This is an activity which carries immense risk because driving really attracts muppets who can't. After a while I could evaluate the "pupil" within 30 seconds of meeting them - and adjust our session accordingly.
Your question is redundant and an insult to the many good & excellent helicopter instructors.
